| Summary: | The present invention relates to a battery charger for charging a battery, said battery charger comprising an AC/DC power supply means, a pulse width modulation controlled DC/DC converter and a control unit that is connected to the AC/DC power supply means and the PWM-controlled DC/DC converter. The battery charger has a maximum output power while avoiding to blow up small battery packs if the control unit is adapted to measure at least a voltage and a current at terminals of the battery to be charged, calculate a power at the battery, compare the calculated power and the nominal maximum power of the AC/DC power supply means, and transmit a signal to the PWM-controlled DC/DC converter to adjust a charging current supplied to the battery based on the comparison result. A temperature at the battery can also be measured. |
